Artstation Challenge - Poster & Lineup

Poster done for the Lightbox Expo challenge
I enjoyed building this mysterious world through the characters. Some lines about the story:
One of the highest mage infringed the law: He did a pact with a demon. He will gain incommensurable power if he brings enough mages to quench the thirst of his demon.
But the other mages won't give up that easely, and everyone starts to pact with various demons. This is the begining of 1000 years of war.
I think I will make a personal project from this universe and redraw all of them in a futuristic twist !
